8mm TCW Core Pro wire sets are purpose-built for racers and enthusiasts running Vertex® magnetos or point-type ignition systems. Featuring a tinned copper solid core with 0 ohms per foot resistance, these wires deliver maximum spark energy with zero signal loss. An 8mm silicone outer jacket provides heat protection up to 600° Fahrenheit, while the silicone inner core adds an extra layer of thermal defense and maintains superior flexibility over the lifetime of the wire.

Race Fit wires arrive cut to exact length and fully terminated — boots and terminals installed on both ends, ready to drop straight in. Note that lengths are optimized for the chosen routing path; if you're running a fixed loom or an alternate wire path, fitment may vary. An extra-long coil wire is also included, one end fully prepped and the other left open so you can trim to length and finish with the boot and terminal to your high-performance coil of choice.
